Abstract
A search for the lepton-family-violating decay eta-->mu e and the rare decay eta-->e(+)e(-) yields the following branching ratio (B) upper l imits at a 90% confidence level: B(eta-->mu e)<6X10(-6) and B(eta-->e( +)e(-))<2X10(-4). This is the first direct search for eta-->mu e The m easurements were carried out at the SPES2 tagged eta facility at Labor atoire National Saturne in the course of a measurement of B(eta-->mu()mu(-)).
